Beschreibung
Zusammenfassung:	An electric dewatering device for pretreating high-water crude oil in oil field is characterized by use of semiconductor electrode or the metal electrode coated with semiconductor layer for preventing the over-current caused by the high electric conductivity of crude oil due to high water content and the over-drop of voltage. Its advantages are high effect on removing water and salt, and saving electric energy by 50%.
